I apologize if this has been covered - I was not able to find a discussion with a solution that works for me. Basically, per the subject, I have a 64-bit Fedora 19 machine with kernel 3.10.3 and VMware Workstation 8. Following the instructions at https://wiki.archlinux.org/index.php/VMware#3.10_kernels VMblock builds fine, but VMnet still fails:

A developer I am not, so I'm sort of lost as to what exactly is causing the issue, but there appears to be something in the file netif.c 
Thank you in advance for any help.
